weight of the member and, of necessity, are cumbersome. Furthermore, thecounterbalances must be positioned in a place which is not easilyaccessible and where it would not be easy for the ordinary layman torepair. Furthermore, the installation of eounterbalances usuallyrequires the services of skilled labor adding to the cost of performingthe job. When one of these systems has been installed, it usuallyperforms only this one function of forming a means for adjusting theposition of a member within a frame and neither prevents rattling, whichis usually found in all such systems, nor does it serve as a weatherstripping in such a case as when a sash is mounted in a window frame.Among the several objects of this invention are to provide devices andmethods for overcoming the above mentioned difficulties.

Referring now to the drawings in detail, there is shown in Figure l awindow frame generally indicate-clat it which is preferably constructedof wood or the like although a metal frame may be used. Window frame Itmay be constructed in the usual manner having a pair of stiles l I, atop portion l2, and a sill 43 all of which are secured together by anysuitable means such as by screws or nails.

Preferably near the center of stiles H and secured thereto I have placedguide strips it. Guidestrips Hi preferably extend from the top portionl2 to the sill l3 and have their sides 95 and I7 (Figure 3)perpendicular to the stiles H. Secured to the outer edges l5 of thestiles l i and extending inwardly toward the center of the frame l0beyond the inner surface 29 of the stile I! are cover boards IS. Thesides I!) (Figure 3) of the cover boards iii are preferably parallel tothe sides IE of the guide strips It and thus guide strips l4, stiles I land cover boards l8 form tracks on opposite sides of the frame l5)within which sash 2! may slide, its movement in one direction beinglimited by the top portion l2 and in the opposite direction by the silll3.

Between the sides 22 of the sash 2i and the surface 29* of the stiles Hthere is a space 23 (Figure 3) which extends for the length of the side22 of the sash 2i and is rectangular in cross section. The width of thisrectangle preferably is a great deal smaller than the length which isthe width of the stile H between the side l5 of the guide strip I l andthe side iii of the cover board if! such as is usually found inconstructions of this type. I

Within this space 23 and preferably extending longitudinally between thetop portion l2 and the sill l3 and in the track within which the sash 2|slides, I place a resilient strip 24 preferably constructed of metalsuch as stainless steel. Preferably this strip is concave in crosssection having its convex side toward the side 22 of the sash 2| andbetween its two edges 25 and 26 having less length in crosssection thanthe space between the guide strip H and the cover board I8. Preferablythe width in cross section of this strip when positioned upon the stileII is sufficiently greater than the width of the cross section of thespace 23 so that the strip 24 will be compressed by the sash side 22against the stile H and exert a resilient force against the side of thesash.

Preferably, the inner edge 25 of strip 24 is turned upwardly away fromthe stile to form a lip 21!. This prevents friction between this edge ofthe strip and the stile when the strip is compressed by the side 22. Theopposite edge 26 of the strip 24 is preferably secured to the stile byany suitable means, as by a wedge shaped nail 28. If this type of nailis used and the strip is not punched for the nails, the edgesimmediately surrounding the nail as it is driven through the metal willbe bent inwardly (Figure 3) and into the stile forming a very secureconnection. These nails 28 would be driven through the strip 24 atsuitable intervals (Figure 2) to hold the edge of the strip securelyagainst the stile. Thus, I have provided a resilient strip preferablyconcave and constructed of resilient sheet metal capable of beingattached to the stile H of a window frame and lying in the track inwhich the sash 2i slides. Also this strip 24 is suficiently concave asto be compressed by the side of the sash 2| when it is in position thusexerting a resilient force against the side 22 of sash 2| holding thesash in any desired position upon the tracks in the frame.

Immediately below the edge of sides 22 the compressing force exerted bythe sash 2| upon the resilient strip will be released and the strip willresiliently stand out forming stops 29. These stops 28 will always beimmediately below the lower edges of the sides 22 wherever the sash 2|may be placed within the frame I and therefore will form a second meansfor holding the window in any desired position within the frame.

The strips 24 which I have thus placed between the sides of the sash 2|and the stile II also form a very effective weather stripping. As thestrip is attached to the stile II, a tight connection will be formedbetween the two, and when the strip 24 is compressed by the sash 2| thestrip will exert a constant resilient force both against the stile H andthe side of the sash 22, effectively sealing this aperture whichordinarily exists between the sides of the usual sash and stileconstruction. Also because of the constant resilient force exerted bythe resilient strip against the side 22 of the sash, the sash will beprevented from rattling or vibration as the resilient force willcounteract any movement of the sash caused by the wind or vibration.

Thus, this resilient strip 24 which is preferably concave but may takeany other desirable shape not only serves as an effective stop for thesash but also serves both as weather stripping and as an anti-rattler.

Referring now to Figure l, one of the many possible modifications of thestrip 24 is shown attached to stile and exerting pressure against theside 22 of the sash 2| which is compressing it. This type preferablyconsists of two parts 30 and 3| concave in cross section connected by aconvex portion 32 all of these surfaces preferably being pressed fromone resilient metal strip. This forms two surfaces pressing against theside 22 of the sash 2| and leaves a portion 32 which may be securelyattached to the stile by nails 28 or by any other suitable means.

A second modification is shown in cross section in Figure a channel 33having been cut into the edge 22 of the sash 2| and a concave metalstrip 24 having an upturned lip 2'! is secured in this channel so thatthe concave surface of the strip 24 faces the sash and the convexsurface abuts against and is compressed by the stile II when the sash isin position against the stile. To prevent the upper and lower edges 39of the concave strip 24 from digging into or forming undue friction withthe stile II as the sash 2| slides in its track, I preferably secure theends of the strip to the ends or sides of the stile. In Figure 6, I haveshown the edges 39 of the strip 24 secured to the side of thevsash at41! and secured to the end of the sash at 4|. The edges are secured byany suitable means such as by nails 42.

Referring now to Figure '7, I have shown a series of cut-out portions 34in the side 26 of the strip which is to be secured to the surface onwhich the strip is to rest. These cut-out portions, which are preferablyin the shape of triangles, are cut through strip 24 only on two edges 35and 36 and then bent downwardly using the third edge 31 as an axis toform a series of pointed lugs 38 (Figure 8) preferably perpendiculartothe plane drawn between the edges 26 and 27 of the concave strip 24.These lugs will form an efiicient means for attaching the strip 24 toany surface. modifications for placing and shaping the strip each ofwhich will perform the unique function of acting as a stop for a sash ina window frame, an effective weather strip, and an anti-rattler. And Ihave also provided an efiicient and in-, expensive means for attachingthe strip to a surface.

It will now become clear that with my unique and simple device andmethod, I am able to perform three definite functions in holding asliding member at any desired position within its track, sealing theaperture between the sliding memher and its track, and preventingexcessive lateral movement of the member as would cause rattling of themember within its tracks. It is to be understood that each of thesefunctions is of independent value and the construction may be arrangedto accomplish anyone or more of them as an embodiment of features of theinvention. Furthermore, it will be noted that this has been accomplishedin a simple and efficient manner by a device which may be manufacturedat extremely low cost. All of the factors accomplished by this deviceoffer material advantages in the production of this device and to theuser.

It will thus beseen that I have provided a thoroughly practical devicefor holding a sliding member within its frame at any desired position inwhich the several objects hereinabove mentioned as well as many othersare successfully accomplished.

As many possible embodiments may be made of the above invention and asmany changes might be made in the embodiment above set forth, it is tobe understood that all matter hereinbefore set forth, or shown in theaccompanying drawings, is to be interpreted as illustrative and not in alimiting sense.
